30 years later and I'm headed back to the wilderness. So I dig out my 70's Svea 123 and go to test it. (using mini pump with required cap) So I'm pumping away and determine that the seals and/or O-rings are failing on the pump. But I get enough pressure to get something to come out the nozzle, but it's shutoff. I verify it's shutoff and go back to pumping with gusto, and again, fluid leaks out the nozzle enough to light, but that's all it had in it. (Probably due to bad cap seal). So I've ordered a mini-pump repair kit (old cap washer crumbed out). But I'm not sure what I'm looking for to ensure proper shutoff. I've seen mention of perhaps a "granite" washer for the adjusting rod? That seems that might be what I'm needing, but any insights would be appreciated.
